Patented Aug. 12, 1930 PATENT OFFICE WILLIAM A. THOMPSON, OF NORTHLANDMINES, ONTARIO, CANADA INTEBCHANGEABLE SKATE Application filed May 27,

This invention relates to the class of skates, and more particularlyrelates to tubularice skates.

The principal object of the invention is the production of a combinationof parts well suited for economical manufacture, which may be utilizedto produce a skate suitable for racing, a skate suitable for pleasureskating or for hockey, and a skate suitable for figure or fancy skating.

The nature of the invention and its distinguishing features andadvantages will appear when the following specification is read inconnection with the accompanying drawing, in which- Figure 1 is a sideView of a racing form of skate constructed in accordance with theinvention, ortions being broken away to show certain structuralfeatures.

Fig. 2 is a side view of the heel plate and connected plug.

Fig. 3 is a side view of the sole plate and connected plugs.

Fig. 4 is a side view of the runner structure and connected sockets.

Fig. 5 is a section taken on the line 5-5 of Fig. 1.

It is to be understood that the invention contemplates a combination ofparts which will include runners of different forms namely a runner forracing, a runner for pleasure skating or for hockey, and a runner forfigure or fancy skating. Each runner is secured to a main part oftubiform having attaching 3 hoses. The runner and tubiform part willconstitute a unitary structure adapted for application thereto of otherparts to be hereinafter described to constitute a skate of one of theforms mentioned.

Referring now more particularly to the drawing, it will be apparent thatthere has been shown a main tubiform part 10 having depending flanges 11embracing and secured to a runner. As shown in Fig. 1, the runner 12 issuitable for racing, whereas the runner 13 shown in Fig. 4, is suitablefor figure or fancy skating. Obviously other forms of runners may beprovided which will be suitable for pleasure skating or suitable forhockey. The tubiform part 10 has secured 1929. Serial No. 366,437.

or brazed thereto bosses 14, 15 and 16 of desired shapes andproportions. Each boss has a threaded hole 17. Use is made of hollowparts or sockets 18, 19 and 20 of the desired shapes and proportions.Use is also made of hollow parts or plugs 21, 22 and 23 adapted forassociation respectively with the parts 18, 19 and 20.

The parts 18 and 19 are identical, each being, in the form of atruncated cone having a lower integral end wall 24 with a hole 25therein. The part 20 is cylindrical and also has an end wall and holelike the parts 18 and 19. The parts 18, 19 and 20 are adapted to bedetachably secured respectively to the bosses 14, 15 and 16 by headedscrews 26. Each screw 26 is projected through the hole 25 in the relatedpart and is screwed into the threaded hole 17 in the related boss, thehead of the screw being brought into engagement with the end wall 24. v

The parts 21 and 22 are identical, each be ing in the form of an openended-truncated cone. The part 21 is secured in any suitable manner to ashoe or boot attaching plate 27, the same being the heel plate, whereasthe part 22 is secured in any suitable manner to a shoe or bootattaching plate 28, the same being the sole plate. The part 23 iscylindrical to conform to the part 20, and said part 23 is open at eachend. The part 20 is secured to the sole plate 28 in any suitable manner.

In order to detachably and turnably conneet each of the parts 21, 22 and23, individually with the related parts 18, 19 and 20, each of the parts21, 22 and 23 and said parts 18, 19 and 20 has coacting means in theform of threads 29 on the said parts-18, 19 and 20 and threads 30 on theparts 21, 22 and 23. It will therefore be understood that the part 18 isadapted for threading engagement with the part 21, the part 19 isadapted for threading engagement with the part 22, and the part 20 isadapted for threading engagement with the part 23.

To assemble the parts of a skate the parts 18, 19 and 20 are connectedwith the parts 21, 22 and 23; after which the screws 26 are driven hometo connect the parts 18, 19 and 20 respectively with the bosses M, 15and 16. In this manner the heel and sole plates are detachably connectedWith the desired runner to constitute a skate of the desired form.

I claim:

1. A skate having the combination of a runner member, a boss integralWith said runner member and having a threaded hole, a socket, a screwengageable with the lower end of the socket and adapted for threadingengagement in said hole to detachably secure said socket to said boss, ahoot or shoe attaching plate having a hollow plug, and coacting means onthe socket and plug to detachahly secure them together.

' 2. A skate having the combination of a runner member, a socket, afastening element to detachably secure said socket to said runnermember, a boot or shoe attaching plate having a hollow plug, andcoacting means on the socket and plug todetachably and turnahly securethem together.

3. A skate having the combination of a runner member, a socket, afastening element to detachahly secure said socket to said runnermember, a boot or shoe attaching plate having a hollow plug, andcoacting threads on the socket and plug to detachably secure themtogether.

4. A skaw having the combination of a runnerv member, a cone-shapedsocket, a {as tening element to detachably secure said socket to saidrunner, a boot or shoe attaching plate having a hollow cone-shaped plug,and coacting means on the socket and plug to detachably secure themtogether.

5. A skate having the combination of a runner member, sockets, fasteningelements to detachably secure said sockets to said runner member, hollowopen-ended plugs, there being one plug for each socket, coacting meanson each socket and its plug to detachabl secure them together, and meanscar.- rie by the plugs for securing the skate to a boot or shoe.
